About DNS Propagation
TTL Controls Speed
Lower TTL values mean DNS resolvers cache records for less time, accelerating change propagation globally.
Up to 48 Hours
Most DNS changes propagate within minutes to hours. Full global propagation can take up to 48 hours for high-TTL records.
Inconsistency
Seeing different values across locations is normal during propagation. Values align once all resolver caches expire.
Pro Tip
Lower your TTL to 300s (5 min) 24 hours before DNS changes to minimize downtime during domain migrations.
